A hydraulic mount for a vehicle includes: a core bush coupled to a bolt; a main rubber formed on an outer surface of the core bush; an orifice portion coupled to a lower portion of the main rubber to divide an upper fluid chamber and a lower fluid chamber; and a lower rubber film coupled to a lower portion of the orifice portion. The orifice portion includes an upper nozzle plate formed with a first fluid inlet and outlet port, a lower nozzle plate formed with a fluid path and a second fluid inlet and outlet port, and a cylinder-type membrane vertically arranged between the upper nozzle plate and the lower nozzle plate, and a pattern of crests and valleys is formed along a circumference of the membrane, the pattern of crests and valleys selectively contacting the upper nozzle plate and the lower nozzle plate.

Hydraulic mount for vehicle

Disclosed herein is a hydraulic mount for a vehicle, wherein a serpentine wall that protrudes from a bottom surface of a membrane wherein the membrane operates as a bottom surface of the upper chamber, is bonded to an orifice lower plate and separates a central chamber and a serpentine inertia track. Furthermore, the serpentine inertia track is disposed along a circumference of the central chamber. The hydraulic mount additionally includes a plurality of orifice apertures that are formed in the orifice lower plate and configured to allow communication between the central chamber and the lower chamber.

A vibration absorbing mounting device may include an outer housing, a mounting shaft, a core, a first nozzle valve spaced apart from and disposed below the core, an inner housing spaced apart from one side and the other side of the core, with the first nozzle valve being mounted to the inner housing, and a chamber separator fixed to the core and brought into close contact with and sliding on the first nozzle valve, wherein the chamber separator forms a first chamber and a second chamber, and an elastic member formed between the core and the inner housing and between the inner housing and the outer housing, wherein fluid is filled in the first chamber and the second chamber, and a first nozzle fluidly-connecting the first and second chambers is formed in the first nozzle valve.
